   • Awọn ipare-jade ti ohun kan
   • Apapọ ariwo orin kan
   • Ipari orin kan
2. What does spectral flux measure for onset detection?
   • A rule that marks every beat as a note onset
   • Positive increases in spectral energy between successive frames
   • A decay detector that selects only falling energy
   • A pitch estimator that finds the nearest MIDI note
3. Kini idi ti atunṣe idaji-igbi ti a lo ni ṣiṣan iwoye?
   • Lati mu awọn ibajẹ pọ si
   • Lati yi ohun pada si ọrọ
   • Nitorina awọn iyipada agbara ti nyara (rere) nikan ṣe alabapin, kọju awọn ibajẹ
   • Lati fa fifalẹ ohun ohun
4. Iru ibẹrẹ wo ni o nira julọ lati ṣawari?
   • A didasilẹ ilu lu
   • Ijamba kimbali ti npariwo
   • A pakute backbeat
   • A rirọ, mimu fayolini wú

   • Double-nfa ati eke ibẹrẹ
   • Audio funmorawon
   • Iyipada ipolowo
   • Sitẹrio gbooro
6. What can a neural onset detector learn from labeled audio examples?
   • A guarantee that every onset will be detected
   • Patterns in the audio features that signal event beginnings
   • A fixed tempo that applies to every recording
   • The identity of every instrument without evaluation
7. What does onset backtracking do when detected times are used to create audio slices?
   • Moves each onset to the end of the entire recording
   • Replaces each onset with the nearest musical beat
   • Moves an onset to the nearest preceding local minimum of an energy signal
   • Adds a fixed one-second delay after every peak
8. What can happen when an onset model is transferred to a different instrument or dataset?
   • Its predictions are guaranteed to remain identical
   • The audio automatically becomes monophonic
   • The model no longer needs a time-frequency input
   • Its performance may change and should be evaluated in the new domain
